WATER-GATE.

SPECIFIGATION forming part of Letters Patent No. 323,562, dated August 4, 1885.

Application filed June 2, 1885. (No model.)

To all whom it may concern:

Bc it known that I, CLEVELAND J. CHENEY, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in VaterGateS; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specication.

rihis invention relates to an improvement in ilood or sluice gates such as are used in the t'orebays of mills, penstocks, or similar waterconduits to regulate the discharge of the water, the object being to provide a gate whose manipulation may be more convenient and easy than that of other forms now in use, and whereby the usual excessive friction of sliding bearings in water-gates may be avoided; and the invent-ion consists of any ordinary siuice-gate having fastened thereto a frame-work provided with wheels, and having a system of leverage whereby the gate may be lifted from its seat and caused to bear upon this locomotive frame-work in suoli a manner as to be vertically or horizontally movable.

in the an nexed drawings, illustrating my invention, Figure l is a front view of my improved water-gate. Fig. 2 is a side view, and Fig. 3 a top view, of the same.

A represents a water-gate, constructed in any ordinary and familiar fashion, of astrength sufficient to withstand the head of water coming from the miltraee or other water-course,

lasps L L L L, attached to the gate and running loosely over the axles B B. Upon the ends of the axles are placed wheels K K K K, which move in the same plane upon which the gate rests at M. Y

C C C C are four combinationlevers, connected near the middle of the frame with an eye-hook, F, whence they radiate to the corners of the frame, where their extremities rest on pivots on the cross-bars E E. D D D D are straps or clasps for attaching these levers C to gate A, and they are securely fastened to the gate and pass over the top of the levers. A long lever, G, engages with the eye-hook F, and is fulcrnmed on the axle B at N. lVhen the far end of this lever is depressed, the hook Fwill be raised, and with it the inner ends of the levers G C C C. These levers, since they are fastened to the gate Aat D D, will be elevated slightly at D D, and will remove the gate from its seat on the sides M M of the water-way I) to that extent.

H is a start attached to the upper edge of the gate, and it operates the gate by lifting or lowering the same.

The operation of the gate is as follows: The lever G is depressed toward the gate, so as to act upon the combination-levers suflicicntiyto lift the gate from its position one-half inch, more or less. This leaves it clear of contact with the slides, and at the same time lifts it onto the vertically-moving car, or, what is the same thing, suspends it therefrom byA the strap connections D D D D of the levers. New, by any suitable means, the lever G may be fastened into its depressed position, after which, by suitable mechanism provided, as the lever in Fig. 2, attached to the start', this start can be raised, when the car will roll easily upward, and the gate be removed from the sluiceway.

In large gates, if desired, screws or cams may be used for lifting the gate from its seat, instead of the levers l have described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A water-gate consisting of a gaie, a locomotive frame-work, and a system of leverage for lifting the gate from its seat onto the frame-work and for moving the same, substantially as shown and described.

2. In a water-gate, the combination of a gate, A, having start' H, and a qnadriiateral frame-work joined thereto by clasps L, provided with wheels and serving,` as averticallymovable car, the said gate adapted to be lifted onto the car by means of Aa lever, G, fulerumed on one axle, and levers C C C C, connected therewith by an eyebolt, F, and fulcrumed on the cross-pieces E E, and attached to the gate at D D D D, all arranged and operating substantially as shown and described.

3. In awater-gate, a system of levers for lifting` the same from its seat, which is composed of a main lever, G, engaging with an eyehook, F, to which are united four levers, C C C C, fulcruined at points on cross-beams E E,
